As I said don’t hammer the survivors or you have no chance. You used to be able to go hard at them and they would recover well but not anymore with RVHD, I have noticed if you take to many they take years to get back. I barely use a net anymore just bolt to the dog, he misses loads but that means they are there to breed. Ferreting with purse nets or well set long nets is a brutally effective method of pest control.
